Our research centers on the design and development of functional organic/inorganic nanocomposites and biomaterials, focusing on their physical and chemical property characterizations. Our work involves the characterization of physical properties of polymers and soft matter used in diverse industries, aiming to understand and replicate their unique physicochemical behaviors through the engineering of filler/matrix interfaces. We are studying various types of acrylic and epoxy-based debond-on-demand adhesives, as well as battery cover films with fire-retardant capabilities to enhance the recyclability of batteries and prevent catastrophic fire accidents for electric vehicles. We also design programmable materials inspired by nature, such as unique hierarchical systems found in hair or bone. One example is the load-induced fluid flow systems and vascular architectures that mimic the lacunar-canalicular network in bone. We employ interdisciplinary methods based on mechanical, chemical, physical, and materials science knowledge, including material property characterizations, computations (molecular dynamics simulations, machine learning, parametric modeling, etc.), and advanced fabrication technology (3D printing and robotic experimentation) to explore the relationships between external environments and internal architectures. Another example is the study of applying biogenic materials, like beeswax, as sustainable alternatives to conventional light fixtures, integrating materials design with sustainability. Advancing programmable metamaterials through machine learning-driven buckling strength optimization is also among our very interesting research topics. Our group emphasizes the convergence of materials physics, engineering, and design to develop innovative solutions in mechanical engineering.
